    Player_Name = models.CharField(max_length=100) 
    Nick = models.CharField(max_length=100, blank=True) 
    Jersy_Number = models.IntegerField() 
    Team_id = models.ForeignKey('Team')

) 
    Poistion = models.CharField(max_length=1, blank=True, choices =Postion_Choices) 
    Red_card = models.IntegerField(blank=True, null=True) 
    Yellow_card = models.IntegerField(blank=True, null=True)

    pass 

#def __unicode__(self): 
    # return Team_Name 

#def save(self, force_insert=False, force_update=False): 
    # pass 

@models.permalink 
def get_absolute_url(self): 
    return ('view_or_url_name') 


class TeamAdmin(admin.ModelAdmin): 
    list_display = ('Team_Name',) 

    search_fields = ['Team_Name',] 

admin.site.register(Team, TeamAdmin)

Answer 1

你就要成功了，你有评论出来，忘了打电话给正确的属性：

def __unicode__(self): 
    return self.Team_Name 

阅读documentation。

Answer 2

添加unicode方法球队对象：

def __unicode__(self): 
    return self.Team_name 

Answer 3

而且更新的开发人员（Python 3.x都有）：

def __str__(self): 
    return self.Team_name
